Initially, Oma is expected to track across the northern part of New Caledonia. Where it goes then depends on which weather model prevails.

"All models agree with it going south west over the next few days," Sky News Weather channel meteorologist Tom Saunders said on Tuesday.

But it increasingly appears it could then head towards the west on a collision course with Australia.

"It could be over south east Queensland coast at the weekend."

That's the conclusion of Europe's EC weather modelling. But a number of other global meteorological associations have made a punt it will change direction as it heads towards Australia, which mean it could avoid landfall.

"The most likely scenario at this point is that Oma will stay offshore," Mr Saunders said.

"But we cannot rule out a coastal crossing this weekend and if that happens it means heavy rain for the southern Queensland coast and Brisbane.

"It could bring damaging to destructive winds and the swell will be huge whether or not it hits the coast."

Mr Saunders said the large swell was because a cyclone can have a significant effect on water conditions even if it remains far from the coast.

The BOM has issued a severe weather warning for hazardous surf from Tuesday onwards. It said swimmers should consider staying clear of the water and those rock fishing should avoid exposed coastal platforms.

Boaters should take extra care on the water and ensure they have appropriate safety equipment.
